McDermott International Inc., Houston, has reported that one of its subsidiaries has been awarded full engineering, procurement, construction and installation (EPCI) of a 750-ton compressor module for BG Group's Trinidad & Tobago’s (T&T)Hibiscus field development offshore Trinidad. The contract is valued at more than US$50 million and will be included in McDermott's second-quarter 2011 bookings.

“We are pleased to be working for the BG Group again to deliver this full scope compressor module for the Hibiscus gas field, which will enable BG to increase gas supply to its Atlantic LNG trains,” said Stephen M. Johnson, McDermott’s chairman, president and chief executive. “Where we add value to this field development is by providing the full range of engineering and construction services and managing the project interfaces in house.”

Detailed engineering design of the compression module will be carried out by McDermott along with procurement for the module equipment and some specialty items. McDermott’s Morgan City fabrication facility will handle procurement of bulk items and construct the module on site in Louisiana.

Engineering commenced in the first quarter of 2011 and fabrication is due to begin by the first quarter of 2012 – with loadout and transportation scheduled for the first quarter of 2013.

McDermott’s heavy lift vessel DB50 will set the compressor module at the installation site on the existing Hibiscus platform, in a water depth of 500 feet, before performing the compressor module tie-in, hook-up and commissioning on site. The field lies 28 miles off the north coast of Trinidad.

The Hibiscus field is part of BG T&T’s North Coast Marine Area development to supply gas to trains 2, 3, and 4 of Atlantic LNG in Point Fortin, South Trinidad.
